Variable Air Volume Box / Air Terminal Unit

A VAV terminal unit, often called a VAV box, is a zone-level flow control device. It is a calibrated air damper with an automatic actuator. The VAV terminal unit is connected to either a local or a central control system. Historically, pneumatic control was commonplace, but electronic direct digital control systems are popular especially for mid-to-large size applications. Hybrid control, for example having pneumatic actuators with digital data collection, is popular as well.
